4. The method of claim 1, wherein the totem IMU includes at least one of a gyroscope and an accelerometer.

5. The method of claim 1, wherein the EM receiver detects six-degrees of freedom (“6dof”) movement of the EM transmitter relative to the EM receiver.

7. The method of claim 6, wherein the fusion routine executes at a first frequency and the unfused location determination modeler executes at a second frequency that is different from the first frequency.

8. The method of claim 1, wherein the predetermined distance is less than 100 mm.

12. The method of claim 10, wherein a head unit IMU of the head unit detects movement of the head-mountable frame.
